When I set forth with my journey of containerization with docker, I have gone through a misconception that Overlay networking in docker can’t be set up without any orchestrator like Docker swarm, Kubernetes. But after spending some time with containers I realized that I was wrong, Orchestrators leverage the functionality of overlay networking but it is not true that we cannot use overlay networks without any swarm or Kubernetes.

Docker Networking – Containers Communication
In the modern world, the container is a fascinating technology, as it has revolutionized software development and delivery. Everyone is using containers because of its dynamic, scalable, and isolated nature.
People do use some orchestration software such as Kubernetes, Openshift, Docker Swarm, and AWS ECS, etc to run their production workloads on containers.
But the question is how these containers communicate with each other in various situations? Continue reading “Docker Networking – Containers Communication”
GitOps with Jenkins and Kubernetes
While tools like Kubernetes is becoming an essential need for modern cloud-based infrastructure, there is a high potential for cloud-native CI/CD. To achieve that there is a philosophical approach has emerged i.e. GitOps. As we have discussed the important principles of GitOps in our previous blog, So in this blog, we will see how to implement GitOps in our current DevOps processes, and finally GitOps implementation in a light manner. If you haven’t gone through our previous blog, here you can take a look at it.
Why GitOps is so exciting?
Initially, we had the DevOps framework in which Development and Operation team collaborated to create an agile development ecosystem. Then a new wave came with the name of “DevSecOps” in which we integrated the security into the existing DevOps process. But nowadays a new terminology “GitOps” is getting famous because of its “Single Source of Truth” nature. Its fame has reached to this level that it was a trending topic at KubeCon.
Log Everything as JSON
Logging and monitoring are like Tony Stark and his Iron Man suit, the two will go together. Similarly, logging and monitoring work best together because they complement each other well.
